Title: Modification of polymeric substrates using dense or liquified gases

Abstract

A method of modifying a polymeric substrate, such as polyethylene terephthalate and nylon 66, imparts water repellency and lubricity, and provides the additional benefit of reducing the soiling of fabrics. The method includes combining the polymeric substrate with a dense or liquified gas, such as carbon dioxide or sulfur hexafluoride, and a fluorinated compound, such as a fluorinated polyether.

Polybenzimidazole compounds, polymeric media, and methods of post-polymerization modifications

Patent Klaehn, John R [Idaho Falls, ID]; Peterson, Eric S [Idaho Falls, ID]; Orme, Christopher J [Shelley, ID]; ...

A PBI compound includes imidazole nitrogens at least a portion of which are substituted with a moiety containing a carbonyl group, the substituted imidazole nitrogens being bonded to carbon of the carbonyl group. At least 85% of the nitrogens may be substituted. The carbonyl-containing moiety may include RCO--, where R is alkoxy or haloalkyl. The PBI compound may exhibit a first temperature marking an onset of weight loss corresponding to reversion of the substituted PBI that is less than a second temperature marking an onset of decomposition of an otherwise identical PBI compound without the substituted moiety. The PBI compoundmore » « less

Uniformly dense polymeric foam body

Patent Whinnery, Jr., Leroy

A method for providing a uniformly dense polymer foam body having a density between about 0.013 g/cm.sup.3 to about 0.5 g/cm.sup.3 is disclosed. The method utilizes a thermally expandable polymer microsphere material wherein some of the microspheres are unexpanded and some are only partially expanded. It is shown that by mixing the two types of materials in appropriate ratios to achieve the desired bulk final density, filling a mold with this mixture so as to displace all or essentially all of the internal volume of the mold, heating the mold for a predetermined interval at a temperature above about 130.degree.more » « less

Modification of polymeric surface for improved adhesion via electron beam exposure

Patent Kelber, Jeffry A [Paradise Hills, NM]

Treating polymer surfaces, e.g., Teflon, particularly very thin surfaces, e.g., 50-10,000 .ANG. with low energy electron radiation, e.g., 100-1000 eV, in a high vacuum environment, e.g., less than 10.sup.-6 Torr, to enhance the ability of the surface to be adhered to a variety of substrates.
